Division Sharing and Grouping
We will learn division sharing and grouping.
Share eight strawberries between four children.
Let us distribute strawberries equally to all the four children one by one.
After distributing equally among four children, four strawberries were left. They can be further distributed among four children.
Now, there are no more strawberries left in the box. Each child got 2 strawberries. So, division is an operation of repeated subtracted of the same number.
8 – 4 = 4
4 – 4 = 0
Here, we have subtracted 4 repeatedly 2 times until we reached 0.
Hence, 8 strawberries ÷ 4 children = 2 strawberries for each child.
We can also say that 8 strawberries have been divided into 4 equal groups of 2.
So, 8 ÷ 4 = 2. This is called a division fact.
